Initial attempts at measuring the low strain tensile properties of skin led to results which were not repeatable. It appeared that strains induced in the sample due to the handling needed to mount it in a simple clamp led to the low precision of the test. A new method which minimized the manipulation needed to mount a sample in a testing machine was then developed. Using this method the skin was aligned with a set of grips in a saline bath. When aligned, the saline was removed and the sample clamped in the grips without the need for additional handling. This approach produced a marked improvement in the repeatability of the tensile properties of skin at low strains.
最初测量皮肤低应变拉伸性能的尝试得到的结果不可重复。似乎将样品安装在简单夹具中时因操作而在样品中产生的应变导致了测试的低精度。随后开发了一种新方法，该方法将在测试机中安装样品所需的操作减至最少。使用这种方法，皮肤在盐浴中与一组夹具对齐。对齐后，去除盐水，将样品夹在夹具中，无需额外操作。这种方法显著提高了皮肤在低应变下拉伸性能的可重复性。
